At the University there is the lecture hall where the poet Fray Luis de León (1527 – 1591) gave classes, still conserved intact as he left it. The room still contains the benches at which the students would sit, made from un-worked beams of wood. Here he made his famous comment "Como decíamos ayer" (as we were saying yesterday), just after being released from five years in prison, after trial by the inquisition of Valladolid.
